Question
**Hess's Law Simulation**

**Instructions:**
Select a reaction by clicking and dragging it into one of the spaces below.

**Available Reactions:**
1. \( \text{SnCl}_2(s) + \text{TiBr}_2(s) \rightarrow \text{SnBr}_2(s) + \text{TiCl}_2(s) \)
   - \( \Delta H^\circ = +4.2 \, \text{kJ/mol} \)

2. \( \text{SnCl}_2(s) + \text{Cl}_2(g) \rightarrow \text{SnCl}_4(ℓ) \)
   - \( \Delta H^\circ = -195 \, \text{kJ/mol} \)

3. \( \text{TiCl}_2(s) + \text{Cl}_2(g) \rightarrow \text{TiCl}_4(ℓ) \)
   - \( \Delta H^\circ = -273 \, \text{kJ/mol} \)

**Reaction Manipulation Options:**
- Clear
- Reverse

**Net Reaction:**
\[ \text{SnCl}_2(s) + \text{TiCl}_4(ℓ) \rightarrow \text{TiCl}_2(s) + \text{SnCl}_4(ℓ) \]

To achieve this net reaction, you need to utilize the given reactions correctly. When the net reaction has been achieved, press "Check."

**Note:** The calculation for the net enthalpy change (\( \Delta H^\circ_{\text{net}} \)) currently shows 0.0 kJ/mol.

**Student Attempt Feedback:**
- The feedback indicates an incorrect attempt. The instruction is to add Reaction 2 and the reverse of Reaction 3 to produce the desired net reaction.

**Interface Options:**
- Submit Answer
- Retry Entire Group
- Recheck (2 of 4 attempts)
- 10th Attempt Notification
- Remaining group attempts: 9

Ensure you understand the use of Hess’s Law to calculate enthalpy changes by combining known reactions appropriately.
